GIS Analyst at nfoldROI Pvt Ltd. (2024-06 – Present)

• Extracted lanelet and road assets in TopoDOT using LiDAR point clouds and imagery.
• Built and validated lane topology (boundaries, centerlines, merges/splits, stop lines, intersections).
• Ensured geometric accuracy and snapping continuity through visual and checklist-based QA.
• Added and verified lane and regulatory attributes (direction, speed, line type, traffic signs/lights).
• Accurately mapped traffic signals, pedestrian/bike heads, beacons, signs, cameras, poles, controllers, and detection equipment.
• Created and managed QGIS GeoPackage layers with correct CRS, schema, and UUID-based asset IDs.
• Performed QA checks, merged multi-layer deliveries, and exported GeoPackage & GeoJSON datasets per standards.
• Validated Manholes, Fire Hydrants, Road Signs, and Support assets through GIS QA/QC workflows using QGIS and GeoPackage datasets.
• Reviewed and validated assets using QGIS plugin tools, updating status categories (valid, moved, false positive, manual addition).
• Conducted road sign and support layer cross-checks, verifying support types and correcting attribute inconsistencies.
• Applied point-cloud filtering and distance controls for precise asset positioning.

GIS Utility Mapping & Data Maintenance Specialist at nfoldROI Pvt Ltd.

• Worked extensively on GE Smallworld GIS 4.3 for utility asset mapping and database maintenance.
• Mapped and maintained electrical distribution and transmission assets (poles, transformers, switchgear, feeders, substations) using GIS platforms Such as smallworld.
• Performed spatial data validation, topology correction, and network tracing to ensure electrical connectivity accuracy and data integrity.
• Created, edited, and maintained utility network features such as cables, conductors, poles, transformers, pipelines, valves, joints, chambers, and service connections.
• Accurately mapped electrical assets.
• Updated spatial and attribute data based on as-built drawings, redlines, and client documentation.
• Ensured accurate connectivity and feature relationships adhering to utility network standards.
• Performed utility pole classification to distinguish electricity and telecommunications poles based on physical and asset specifications.
• Analyzed pole characteristics such as pole height, material type, cross-arm configuration, conductor count, insulator type, and attached equipment to determine asset ownership.
• Supported asset inventory mapping and quality assurance by tagging poles with accurate ownership attributes in GIS databases.
• Reduced misclassification by applying rule-based specifications and cross-checking against existing utility records.
• Assisted in network planning and utility coordination by providing reliable pole identification for project planning and approvals.

LiDAR Mapping Specialist at IIIT Hyderabad (2023-01 – 2024-05)

• Built real-time LiDAR-based SLAM system for urban mapping.
• Improved localization accuracy under GPS-denied conditions.
• It aims to provide a rich dataset for research in 3D object detection and tracking tasks, addressing the complexities of realworld driving conditions in India.
• Built data annotation and visualization tools for 3D bounding boxes and semantic labels.
• Deployed trained perception models on edge GPU platforms
• Processed LiDAR point cloud data for object detection and scene understanding in complex road environments.
• Implemented 3D object detection models
• Processed multi-object tracking using LiDAR data across frames.
